Abstract

The research about growing pattern, condition factor and habitat of Spotted Barb Barbodes binotatus (Valenciennes, 1842) was done from August until December 2017. The aims of this research are to know growing pattern, condition factor, sex ratio and habitat of Spotted Barb (Barbodes binotatus) in Berambai Forest River. Fishing was done in every month, using purposive sampling method with some fishing gears. The result of the research shows that growing pattern of Spotted Barb (B. binotatus) was positive allometric, the average value of the condition factor was 1,064. The sex ratio of male and female were 1 : 1,06. The Berambai River in good condition for living of Spotted barb.

Abstract

The research was conducted in April-June 2017, located in the coastal waters of Muara Badak, Muara Badak District, Kutai Kartanegara Regency. This study aims to determine the strucure and community of fish in the coastal waters of Muara Badak and to know the types of fish that have economic value in the coastal waters of Muara Badak. Sampling was carried out using the Stratified Sampling method at 3 stations, which used step-by-step fishing gear. Identification of the types of fish obtained is done at the Laboratory of Animal Ecology and Systematics. Biology Department, FMIPA, Mulawarman University, Samarinda. The results showed that there were total fish catches obtained from the three carry net in the coastal waters of Muara Badak consisting of 28 species 19 families, 5 orders of a total of 407,566 individuals. The type of fish found based on the depth level of the coastline of Muara Badak at a depth of 7 meters found a fish community of 16 species from 4 Orders between l Clupeiformes, Perciformes, Syngnathiformes and Tetraodontiformes, at a depth of 8-10 meters to get as many as 23 species of fish The Order, while at a depth of <10 meters, 19 species of 3 Community Orders were most consumed by the people around the Muara Badak, namely Spratelloides gracilis as many as 340,166 individuals. Of the 2 fish species identified 20 species of economically valuable fish, namely: Alectis indicus, Alepes kleinii, Caesio caerulaurea, Caranx sexfasciatus, Chirocentrus dorab, Lutjanus erythropterus, Lutjanus lutjanus, Megalaspis cordyla, Rastrelliger kanagurta, Sardinella gibbosa, Scomberoides tol, Secutor insiator, Selaroides leptolepis, Siganus canaliculatus, Sphyraena obtusata, Spratelloides gracilis, terapon jarbua, Trichiurus lepturus, Ulua mentalis, Upeneus vittatus.

Abstract

Mamalia kecil mempunyai peran yang sangat penting di dalam ekosistem hutan yaitu sebagai penyerbuk, pemencar biji, dan sebagai agen dalam regenerasi hutan, sehingga keberadaannya sangat penting untuk dilestarikan. Adanya alih fungsi penggunaan lahan dikhawatirkan dapat mempengaruhi keberadaan mamalia kecil, sehingga penelitian ini dilakukan untuk mengetahui keanekaragaman dan kelimpahan mamalia kecil non-volant di perkebunan kelapa sawit Desa Setabu Pulau Sebatik, Kalimantan Utara. Penelitian ini dilakukan pada bulan Maret hingga April 2023. Dalam penelitian ini digunakan metode perangkap (Trapping), dengan memasang 40 buah perangkap selama 30 hari pengamatan, Umpan yang digunakan adalah nanas, pisang, kelapa bakar, dan ikan asin. Data yang diperoleh dianalisa secara kuantitatif dan deskriptif. Berdasarkan hasil penelitian ditemukan 7 jenis mamalia kecil yang termasuk ke dalam ordo Rodentia (famili Sciuridae dan Muridae), dengan total tangkapan sebanyak 18 individu. Jenis yang tertangkap yaitu: Callosciurus prevostii, Callosciurus notatus, Chiropodomys major, Rattus tanezumi, Rattus argentiventer, Rattus tiomanicus, dan Sundasciurus lowii. Hasil analisa menunjukkan bahwa keanekaragaman di wilayah ini termasuk ke dalam kategori sedang, dengan kelimpahan individu tiap jenis tersebar merata (sama), serta tidak ada jenis yang dominan.
